Causæ Bibendi, or Reasons to Drink

Here's an interesting question - where did the term "wine flight" come from? Google tells me that I shouldn't use Google to research questions like this.

But, when I do, I'm led to fantastic quotes such as this, a translation of a Latin epigram originally attributed to John Sirmond:

If on my theme I rightly think,

There are five reasons why men drink:—

Good wine; a friend; because I'm dry;

Or lest I should be by and by;

Or — any other reason why.
